My interpretation, and I am probably wrong, is that the left hand side of the
assignment ta(1:8)%c = 8*'bogus'  is an array section but we are currently
trying to assign all the 8 "bogus" strings into the first element of the array
since we have not given any array qualifiers on the right hand side.

I see from your expanded example that gfortran does the same thing NAG does. If
we let gfortran write the namelist, we get this:

&N
 TA(1)%C="bogus   ",
 TA(2)%C="bogus   ",
 TA(3)%C="bogus   ",
 TA(4)%C="bogus   ",
 TA(5)%C="bogus   ",
 TA(6)%C="bogus   ",
 TA(7)%C="bogus   ",
 TA(8)%C="bogus   ",
 /

which is not ambiguous.  I am not arguing either way now, but how does one
interpret these two cases:

 ta(1:8)%c =   'bogus'
 tb(1:8)%c = 8*'bogus'

The first case without the repeat count seems unambiguous to me which leads me
to question the validity of the case with the repeat count.
